Application / Business Specific |
| Consider anyone who has access to the device and the network the device is connected to. | Attacker uses multiple vectors such as capturing update files via unencrypted connections, the update file itself is not encrypted or they are able to perform their own malicious update via DNS hijacking. Depending on method of update and device configuration, attack could come from the local network or the internet. | Insecure software/firmware updates are present when the updated files themselves and the network connection they are delivered on are not protected. Software/Firmware updates can also be insecure if they contain hardcoded sensitive data such as credentials. Security issues with software/firmware updates are relatively easy to discover by simply inspecting the network traffic during the update to check for encryption or using a hex editor to inspect the update file itself for interesting information. | An insecure mobile interface could lead to compromise of user data and control over the device. | Consider the business impact of an insecure mobile interface. Data could be stolen or modified and devices taken control of. Could your users be harmed? Could your brand be harmed? | |

Are My Software Updates Secure?

How Do I Secure My Software Updates?
Ensuring a secure mobile interface requires:
|
|
Example Attack Scenarios
Scenario #1: The interface only requires simple passwords. Example Scenario #2: Username and password are poorly protected when transmitted over the network. Example In the cases above, the attacker is able to either easily guess the password or is able to capture the credentials as they cross the network and decode it since the credentials are only protected using Base64 Encoding.
